Samyama may be applied in various spheres to derive its usefulness

When mastery of integration (samyama) is achieved, the lustre of wisdom and insight shine brilliantly, reconciling the known with the knowable and revealing the self.

Awareness and cognition become firmer and sharper through direct spiritual perception. Ordinarily, our intelligence flits from object to object and from place to place, making it impossible to penetrate fully any one thing. In samyama, the knower comes closer and closer to the known and, merging in it, loses his separateness.

Patanjali explains that this insight and wisdom are to be properly distributed in the various spheres of one's life.

Samyama can be applied in various spheres. In samadhi pada, concepts such as pratyaya and various aspects of sampraajata samadhi and nirbija samadhi

 But one who has not mastered the lower stages cannot attain the higher, nor can he skip the intermediate stages. If each stage is followed in turn, one becomes acquainted with them by degrees and full insight develops.

Full insight may also dawn by the grace of God, won through one's previous virtuous karmas. Vamadeva, Prahlada, Sukadeva and Ramakrishaa in the past, and Aurobindo, Ramana Maharshi and Mahatma Gandhi of the present century were such great personalities who had the blessings of God and attained fullness of knowledge.

This sUtra affirms that no-one can expect success or mastery without regular practice, and also warns one not to jump to higher stages of practice without first establishing a firm foundation through the primary steps of yoga
